REED FOR WIRE-MESH MAKING.

Application filed June 4, 1925.

The main object of this invention is to provide a reed for crimping the cross strings of Woven wire. From experience, it has been found that the warp strings of a wire mesh are easily fractured by various strains of the mesh. It has also been found that crimping the cross strings as they pass between the warp strings makes a wire mesh much less liable to having its warp strings fractured. To accomplish this crimping of the cross strings, the novel type of reed illustrated herein is provided.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure 1 is a front elevational view of a section of the reed, showing the groove or channel in its most desirable position on the reed.

Figure 2 is a sectional elevational view taken on line 2-2 of Figure 1.

Figure 3 a perspective view of a number of reed blades, showing the particular method of aligning the cut-out portions to form a V-shaped groove.

Figure 4: is an illustration showing the position of the crimping device preparatory to its use on a weft string.

Referring in detail to the drawing, the numeral 10 indicates the warp strings of some rigid material such as wire which is interlaced with cross strings 11 by weaving the warp strings and cross strings in the manner shown. These warp strings are easily fractured, due to their great length, especially when used as filters in paper making machinery, in which a wire mesh is used up to a length of three hundred feet. By crimping the cross strings, as shown at 12, it has been found that the warp strings are not as easily fractured. To accomplish crimping in the cross strings illustrated, the reed illustrated in Figures 1, 2, and 3, is provided. This reed consists of a plurality of blades 13 which are rectangular in outline and are provided with spaces 14L between them, said spaces being the thickness of the blade. Into these spaces 1 1, the warp strings 10 are inserted when the wire Serial No. 34,779.

mesh is being woven. These blades are laid upon a steel block 15 and are formed into a reed by securing said blades between pairs of retainer bars 16. Each of the reeds has a semi-circular cut-out portion 17. These cut-out portions are ofi-set on the reeds in such manner that the vertex or intersecting edges of the semi-circular cut-out portions form a Vshaped groove .18 into which groove the cross strings of the wire mesh weave are adapted to be pulled. These semicircular cut-out portions are so positioned on the blades that one semi-circular cut-out portion on one blade is offset half of the diameter of the cut-out portion on the next adjacent blade, as illustrated in Figure 2.

In crimping the cross strings of a wire mesh, the warp strings 10 are inserted into the spaces 1 1 between the blades 13. As a cross string 11 is woven into the wire mesh by passing said cross string under and over successive warp strings, the cross string is drawn or pulled toward the V-shaped groove 18 of the reed. Contact with the intersecting portion of the groove crimps the cross wire between the warp strings, the crimping being illustrated in. Figure 4:.

I claim 1. In a reed for crimping the cross strings of a wire mesh, a plurality of spaced-apart blades, said blades permitting insertion of warp strings therebetween, the blades having semi-circular cut-out portions, said cutout portions being off-set vertically and alternately to produce a series of crimps in the weft in the vertical plane for intimate engagement with the warp wires.
